I just purchased some amazon sword plants. Can anyone tell me about them? I dont know much about taking care of live plants but my Bettas seem to love them so far. I dont even know if I planted them right. Can I plant them directly into the gravel? I know I have the right light bulb for them but thats all I know.

Ive got a couple of them planted straight into my gravel in my 190L tank, they seem to be surviving fine and Ive seen the roots growing through the gravel. As far as I know from reading online they are a pretty undemanding plant can grow in lowish light lvls. Just to be sure maybe stick a fetilizer tablet under or near them in the substrate just to make sure they have food :)
